Application filed March 30, 1909. Serial N0. 486,770.

To all whom it may concern:

B it known that 1, CHARLES VoLL,

tan, county and State of New York, vented certain new and usefulImprovements in Vehicle-Tires, of which the follow ing is a full, clear,and exact specification.

y invention relates to improvements in vehicle wheels and the same hasfor its object more particularly to provide a resilient tire for wheelsdesigned for tion with motor vehicles.

Further, said invention has for its object to provide a tire comprisingan outer shoe and means for maintaining the casing normally distended bymeans series of resilient ranged therein. I

Further, said invention has for its object reinforcing members armeansis composed of a series or plurality of separated members which may heslipped into place and arranged side by side to comtire.

pletely fill the interior of the Further, this invention has for itsobject to provide a resilient tire wherein each resilient reinforcingmember is composed of a plurality of springs arranged one within theother, which pact imparted to the Wheel ties in the road.

Further, said invention has for its object to provide a tire in whichthe resilient reinforcing means is composed of a plurality of sections,each having a series of separated resilient members therein consistingof a set of nested springs.

To the attainment of the aforesaid objects and ends my inventionconsists in the novel details of construction, and in the combination,connection and arrangement of parts hereinafter more fully described,and then pointed out in the claims.

In the accompanying part of this specification, wherein like numerals ofreference indicate like parts, Fig ure 1 is a side view showing a Wheelwith one form of tire constructed according to and embodying my saidinvention; a part of the resilient reinforcing means being shown indotted lines at the upper edge of the wheel; Fig. 2 is an enlargedtransverse section taken on the line 22 of Fig. 1; Fig. 3 is a sectiontaken on the line 3-3 of Fig.

by the inequaliuse in connecof a' a tire in which the reinforcing ointlyserve to absorb the im drawings forming- 15 denotes a casing preferablymade of vulcanized together and to the inner surf canvas or analogousmaterial. Along the edges of said casing 15 are probead flanges 18l8having vertical inner horizontal edges. denote rings or annularmembers disposed upon the outer surface of the beads or flanges 18 18 atthe junction of said beads or flanges with the body portion of saidcasing, and 20 20 clips having projections 21 21 at their lower edgesadapted to engage the underside of the annular plate 14, and similarprojections 22 22 at their upper edges to engage the annular members 1928 denote bolts extending through provided in the under or flanges l8 18supported above the annular plate 14. The numerals 24 24 denote nutsupon the threaded ends of said whereby said clips 20 20 may be firmlyfirm engagement 18 of the casing,

said outer section by parallel rows of stitching, to form a casingadapted to receive an annular or circular rib 25, of rubber or othersuitable material and sides of the beads of said beads in engagementpreferably made substantially semi-circular in cross section.

26 26 denote sectional plates arranged upon the inner surface of theopposing edges of the blades or'flanges 18 18. Each of said sections ismounted upon a flat vertical support 26 arranged intermediate theopposing edges of the beads 18 18, and secured at its lower edge to asegmental plate 26. The opposite edges of each sectional plate 26 areprovided with recesses or grooves 27 27 which are adapted to receive theends of a resilient reinforcing member 28 which has its upper portionconformed to the inner edge of the rib 25 arranged ing 24*, and itssides conformed substantially to the inner surfaces of the shoe 15. Theextremities of each reinforcing member 28 are bent at an angle to themain portion thereof, and are securedwithin the recesses 27 27 of saidsegmental plate 26.

Within the outer resilient reinforcingmember 28 is disposed a second orsupplemental member 29 which is substantially semi-circular in outline,and has its central or intermediate portion resting upon the innersurface of the annular plate 26 and-secured in position thereon by ascrew 29.

The free ends of said supplemental member inwardly, downwardly are bentoutwardly,

and have porand slightly outwardly again,

tions thereof adjacent to their free ends in the casing inclosing thesame.

contact with, and bearing against the curved intermediate portion of themember 28 at a point adjacent to the inner edge of the annular rib 25arranged upon the inner surface of said casing.

In the modification illustrated at Fig. 4 the tire is constructedessentially as here-inbefore described, except that within the outercasing 30, and below the casing 3O containing the rib 31, are arrangedseries of resilient reinforcing members each comprising an outer member32 which corresponds substantially in outline with the interior of 30and within said outer resilient member 32 are disposed a plurality ofresilient members 33 and 34 each of which corresponds substantially inoutline therewith but is somewhat sma ler than the one next The ends ofsaid resilient members 32 '33 34 are brought together and secured videdin the opposite edges of the sectional plates 35 35. Within theresilient member 34 are disposed central or supplemental spring members36 36 which are arranged one within termediate of their ends upon saidsectional plates 35, 35, and are secured in position thereon by a screw'36. The free ends of said supplemental spring members 36, 36 are bentoutwardly and engage the inner surat the sides thereof,

within the easeasing inclosin bracing said annular within the groovesprothe other and rest at a point 1nand also engage the said innercasing,

same below the casing 30 directly below the inner edge of the annularrib. The sectional plates 35 35 are also mounted upon vertical supports35 35 which are arranged intermediate the opposing edges of the beads orand secured at their lower plates 37 which are disposed upon an annu thewheel 10.

When it is desired to set up a tire it merely becomes necessary toinsert the" required number of segmental plates in position within theshoe 15, and the beads or flanges 18 18 of the shoe are then broughttogether upon the annular plate 14 of the rim 11,
